In an upcoming episode, Tisdale won't be pulling a Clarkson and playing herself. She will play Kelsi, an intern at the advertising firm run by father-daughter duo Simon (Robin Williams) and Sydney (Sarah Michelle Gellar). She isn't just any old coffee-fetching intern, though: Kelsi just so happens to be the daughter of one of the agency's biggest clients.

"The Crazy Ones" guest role is the latest in Tisdale's list of recent appearances. She previously showed up on ABC's "Super Fun Night" as Rebel Wilson's sister, and has made guest appearances on "Sons of Anarchy" and "Raising Hope."
